Taylor Swift has a devilish grin as she crashes Miles Teller and Keleigh Sperry’s wedding on TikTok

She’s in the midst of a whirlwind publicity campaign following the release of her rerecorded version of her 2012 album Red.

But Taylor Swift took a moment to share a lighter look at the new album in a humorous behind-the-scenes clip from her new I Bet You Think About Me video that featured Miles Teller and his wife Keleigh Sperry.

The 31-year-old country superstar–turned–pop icon also announced Wednesday that she’d recorded a new ‘Sad Girl Autumn’ version of her newly unearthed 10-minute breakup song All Too Well. 

Having a laugh: Taylor Swift, 31, looked hilariously devilish in a funny behind-the-scenes TikTok posted Wednesday with friends Miles Teller and Keleigh Sperry from her I Bet You Think About Me video

Taylor’s video showed Miles and his real-life wife Keleigh being filmed for the I Bet You Think About Me video, which was directed and cowritten by Taylor’s friend Blake Lively.

Miles wore a black velvet tuxedo jacket and leaned in for a kiss with his wife, who wore a gorgeous white ruffled wedding gown with a voluminous skirt. 

The clip was soundtracked to cheerful yet eerie synthesizer music, and the caption hinted at something more sinister.

‘The chances of your wedding being ruined by a psychotic ex are low,’ it read.

But then the camera panned to the left to reveal Taylor as the ‘psychotic ex’ while she hid behind a carved stone column.

‘But never zero,’ the red-tinted caption now read.

Taylor flashed a hilarious devilish grin and wore a tiny red pillbox hat with her crimson suit as she jealously glared at the lovebirds.

There was no trace of her dark energy in her caption, though: ‘Miles and Keleigh thank you for making this video so magical, I LOVE YOU !!!!’ 

I Bet You Think About Me is a rare return to country music for Taylor, who has mostly transitioned into a pop star, though last year’s albums Folklore and Evermore both featured a healthy dose of arty folk-inspired productions as well.

The track, which features acclaimed backing harmonies from Chris Stapleton, is one of the many bonus tracks on Red (Taylor’s Version), the rerecorded and expanded version of her 2012 album.

The new version is meant to supplant the original after Scooter Braun bought up all of Taylor’s master recordings up through 2017’s reputation.

By rerecording the albums, she’s allowing her fans to purchase and stream the new versions, which will profit her rather than lining Braun’s pockets.

Although Miles is featured extensively in Taylor’s new video, Keleigh has a much more muted presence int he music video.

However, that didn’t stop her from gushing about what a great time she had filming it with the singer.

On Wednesday, she posted a photo to Instagram of herself sitting on the floor in a white cardigan and pink pajamas while holding hands with Taylor, who had changed into the same white wedding dress.

‘Story behind this: I watched on as miles and Taylor did the stunning dance sequence and Taylor played all too well 10 minute version for me during. It was a MOMENT,’ she wrote.

At her service: 'Taylor texted me on you guessed it, the 13th of a certain month and asked if she could borrow miles for a project and I said absolutely whatever you need,' she wrote

‘We are MAIM’d indeed [bandaged heart emojis].  I will be your invisible bride any day.’

Keleigh added that Taylor wanted until it was a lucky day to ask about the video. 

‘Taylor texted me on you guessed it, the 13th of a certain month and asked if she could borrow miles for a project and I said absolutely whatever you need,’ she continued. ‘That’s how this all came together, she is an Angel and Blake [Lively] you are a beautiful genius creative director of life!! We had so much fun. Hope you guys enjoyed.’

Miles’ wife also posted a humorous captioned version of the same photo, in which she was labeled, ‘my autumn anxiety,’ while Taylor’s soothing presence was labeled, ‘(Taylor’s Version).’

‘Forevermore a crumpled up piece of paper lying’ here,’ she captioned the image.

Taylor was seemingly unstoppable, and she followed up her I Bet You Think About Me with a third recorded version of her heartbreak ballad All Too Well.

The hitmaker posted some behind-the-scenes black-and-white photos of her and The National’s Aaron Dessner (who produced several bonus tracks on the expanded Red) as they recorded a new stripped-down live version of the song.

The two traveled to the secluded Long Pond Studio in upstate New York to record the track, which was based on the expanded 10-minute version of the song that used her original set of lyrics.

Taylor was seen dressed in black with a pair of headphones over her long blond hair as she recorded her vocals.

Dessner had on a ribbed black sweater and a black ski cap as he played piano in another photo.

‘One of the saddest songs I’ve ever written just got sadder. Drove up to Long Pond Studios to record All Too Well (Sad Girl Autumn Version) with the besties,’ she wrote, tagging Dessner and Jonathan Low, who engineered Folklore and Evermore.

Although the 10-minute version featured on Red (Taylor’s Version) was produced by her longtime recording partner Jack Antonoff, Taylor seemed to want to hear the track with Dessner’s more rock and folk-inspired taste layered onto it.

The new version opened with his somber piano before Taylor popped up with even more emotional vocals than the version on the record.

The song is widely believed to be in response to her short-lived relationship with Jake Gyllenhaal, which only last about three months. 

Critics have praised Red (Taylor’s Version), with several singling out the new longer version of All Too Well as the highlight of the album.

She broke from tradition when she performed the song in its entirety on Saturday Night Live on November 13, even though most musical guests stick to more concise songs. 

Romance:The song, which appeared in a version that was half as long on 2012's red, is widely believed to be about her three-month relationship with Jake Gyllenhaal; seen together in November 2010
